METAL-WORKING MACHINE.

Application filed September 18, 1913.

To all whom it may concern:

Be it known that I, ROY H. Snrrrrr, a citizen of the United States,residing at Cleveland. in the county of Cuyahoga and State of Ohio. haveinvented a certain new and useful improvement in l\letal-\Vo1l ingMachines. of which the following is a full, clear. and exactdescription.

This invention relates to metal working machines. and particularly toautomatic machines for drilling and facing or otherwise operating anirregular or polygonal blanks. such as square or hexagonal nut blanks.

The main object of the invention is to provide a machine wherein thediiferent operations are )erformed on blanks such as of the typespecified, more rapidly. more satisfactorily and less expensively thanwith prior machines.

Further and more specific objects are to provide a construction whereinsubstantially the same cutting speed is obtained in drilling and facinga nut blank without requiring a rotary facing tool, and to provide meansfor inserting a polygonal blank in a rotating chuck or holder.

The above and other objects are attained by my invention which may bebriefly summarized as consisting in certain novel details ofconstruction and combinations and arrangements of parts which will bedescribed in the specification and set forth in the appended claims.

In the accompanying sheetsof drawings which show the preferredembodiment of my invention, Figure 1 is a side view of the machine. Fig..2 is a top plan view with parts broken away, and the major portion ofthe blank feeding mechanism removed. Fig. 3 is an end view lookingtoward the forward end of the machine. Fig. 4 is an end view lookingtoward the rear end of the machine. Fig. 5 is an enlarged longitudinalsectional view of a portion of the machine taken substantially along theline 5- 5 of Fig. 9. Figs. 6 and 7 are detail sectional views on anenlarged scale taken substantially along the lines 6-43 and 7-7,respectively. of Fig. Fig. 8 is an enlarged end view of one of the blankreceiving chucks. Fig. 9 is a transverse sectional vi w of a portion ofthe machine with parts 1n Specification of Letters Patent.

elevation. the section beinc taken substantially along the line 99 ofFig. 5; and Fig. 10 is an enlarged sectional view of a part of themachine, the section being taken substantially along the line 10--10 ofFig. 2.

Themachine includes a suitable bed or frame 11. in the upper centralportion of which is a turret head 12 (see Figs. 2 and 5), in which ismounted a. turret 13 adapted to be rotated or turned intermittentlyabout a horizontal axis by certain indexing mechanism to be referred topresently. This turret carries six chuck spindles 14-, which are equallyspaced about the axis of the turret, and are rotatably mounted inbearing sleeves 14 secured in suitable passageways extendinglongitudinally of the turret or parallel to its axis of rotation. Eachof these chuck spindles has a passageway extending centrally from end toend and enlarged at both ends, and mounted in the passageway is acentral rod 15 which is capable of slight endwise movement, and isprovided at its forward end with an enlarged threaded portion 15 towhich is screwed and locked by a lock nut 15", a chuck sleeve 16. aportion of which is split or cut from its forward. end inwardly at threepoints. forming three segmental chuck jaws 16 which tend to springlaterally outward when the chuck is adapted to be opened to receive orpermit the ejection of a blank; and are drawn inwardly to grip a blank.the three jaws having a central opening of a shape corresponding to theshape of the blank which the chuck is designed to receive. As shown inFig. 8 the chuck has a hexagonal opening 16 which will accommodate ahexagonal nut blank of certain size. If the machine is to operate onblanks of a different size or shape, the

chucks will be replaced with others. suitably designed for the blank tobe operated on. It will be seen that the chuck jaws are taperedexteriorly. and engage a correspond.- ingly ta iered ring 17 fittecltightly in a socket 0 an enlarged head 14 at the for ward end of thespindle 14, the taper on the parts being such that when the jaws aredrawn inwardly by an inward or endwise, movement of the rod 15 the jawswill be compressed. so as to grip the blank. and when the rod and jawsare moved endwise in the reverse direction, the jaws may spreadslightly. The rod 15 is .pulled inwardly and is normally held in inwardposition by means of a spring 18 surrounding the rear portion of the rod15 and located in the rear enlarged part of the spindle opening, saidspring bearing against a shoulder 14 of the spindle and against anabutment in the form of an adjustable nut 15 on the rear end of the rod15.

Each chuck is provided with a blank ejector consisting of a block 19mounted in the chuck sleeve and extending forwardly a short distanceinto the jaws. This ejector block is capable of a slight endwisemovement and is adapted to be given a quick forward movement to eject ablank when the jaws are opened, by a spring 19*, which is locatedbetween the rod and ejector and is compressed by the blank when thelatter is inserted in the chuck, the said spring being located in asocket in the rear end of the block. It will be understood that theconstruction of all the chucks is the same as that described and shownin detail in Fig. 5.

All the spindles are simultaneously and continuously rotated by a maindrive or power shaft 20 which is provided at its rear end with a pulley20, and extends length wise through the major portion of the machine andcentrally through the turret 13.

This shaft 20 is provided just at the rear of the turret with a pinion20", which engages and drives pinions 20 one of which is fixed to therear end of each of the chuck spindles 14. The object of rotating thespindles and chucks will appear presently.

In connection with-this six-chuck turret of a machine such as thepresent, wherein nut blanks are drilled and then faced or crowned, Iemploy two rotary drills, and two stationary facing or crowning tools,the four tools being spaced 60 degrees apart and arranged opposite or inproper relationship with respect to four of the chucks after eachmovement of the turret. In this case the sequence of operations iscarried on in duplicate, or simultaneously on two nut blanks. Two nutblanks are inserted in the two uppermost chucks, thence the turret isturned 120 degrees so as to bring the two blanks in line with the twodrills, thehce it is turned 120 degrees to bring the drilled blank: inline with the two facing tools, and thence it is again turned'120degrees to again bring the same two chucks in position to receive twomore blanks, the faced or crowned nuts being ejected from the chucks asthe latter are being moved from the crowning position to the receivingposition. I wish it to be understood, however, that it is immaterialwhether the operations are carried onjih duplicate, as in this instance,or singly.

The two drills shown at 21 are supported by suitable socketed members orchucks driven by two drill spindles 21 mounted in bearings carried bystandards 21 of a slide 21 (see Fig. 10) mounted in ways of the bed andadapted to be reciprocated lengthwise of the machine to feed the drillsto and through the blanks and thence to retract the same.

Two facing or crowning tools 22 are carried by a standard 22 secured toa slide 22" mounted in ways and adapted to be reciprocated to carry thefacing tools up to and away from the drilled blanks.

The two slides are reciprocated by properly shaped and timed cams 23(see Fig. 1) both secured to a shaft 24 which is directly beneath theshaft 20 and is driven continuously in the manner hereinafter described.The cams 23 are engaged by rollers 23 (see Figs. 1 and 10) carried bypins '23" extending diagonally upward and outward through bosses 23integral with the slides and normally held securely therein by bolts 23,each of which can be removed to permit the removal of the correspondingslide with the parts carried thereby.

The two drill spindles 21 are rotated simultaneously in the samedirection, but in the reverse direction with respect to the diin androller and of the rection of rotation of the chuck spindles by means ofa gear 25 on the forward end of vshaft 20 (see Figs. 1 and 2) and twogears drills are rotated at the same or substantially the samepredetermined speed that the chucks are rotated in the reversedirection. By this arrangement not only is high cut-- tin t speedobtained without rotating the dri ls at an excessively high rate, butboth the drills andfacing tools will out at about the same cutting speedwhich will be made the maximum cutting speed, and this is obtained witha stationary facing tool which is much more effective and desirable thana rotary facing tool. That the cutting speeds of the drill and facingtool will be substantially the same will be apparent when it isconsidered that the average distance of the cutting face of a nutcrowning or facing tool from the center of the nut blank is about twicethe average distance of the cutting face of the drill from the center ofthe blank.

A very important part of my invention resides in the mechanism forinserting the poly onal blanks in the rapidly rotating chuc s. and thispart of my invention and other features closely associated therewithwill now be described. The nuts are fed from two similar hoppers 30,down through two chutes 30*, the lower portions of which are vertical,and the lower ends of which are directly in line with the two uppermostchucks, after each indexing movement of the turret, so that the blanksmay be moved laterally into the same.

The blanks may be fed from the hoppers into the chutes by any suitablemechanism, but in the present case I utilize in each hopper a starshaped member 30 which is turned step by step, and is provided withradial arms which gradually move the blanks into the chutes and keep thelatter well filled with the blanks. These members 30" are moved step bystep by ratchet mechanism designated as a whole by the referencecharacter-30", the pawls of the ratchets being actuated by rods 30connected to a threearmed bell crank 30 which is rocked by an internalcam 31 which is engaged by a roller 30 on the lower end of one arm ofthe bell crank. This cam 31 as well as other cams to be referred toresently, are supported from and operated y a shaft 32 in the plane ofshaft 24, but to one side of the 'center line of the machine. This shaft32 isydriven from the main shaft 20 through a ti ain of gears, includinga pinion 33 on shaft 20 which engages a large gear 33 on a short idlershaft 33, provided with a pinion 33, which is engaged by a large gear 33adapted to be clutched and unclutched from the said shaft 32 on whichthe cam 31 is mounted. As the shaft 32 drives the cam shaft 24previously referred to throu h gearing 34 (see 1 3%. 1, 5 and 9), by uncutching the gear 33" y a conveniently located hand lever 33, the partsoperated or driven from the shafts 24 and 32, in fact all thereciprocating and otherwise intermittently moving parts can be almostinstantly stopped.

Referring again to the mechanism for inserting theblanks into therotating chucks, it will be seen by reference, particularly, to Fig. 5at the lower ends of the chutes 30 are sleeves 35 which extend at rightangles to the chutes and are in line with the two uppermost chucks whenthe latter are in blank receiving position. These sleeves which haveportions of their upper walls removed so that the blanks may drop intothe same from the chutes, are mounted in blocks 36 on the lower frontsides of the chutes and are capable of slight endwise movement therein.The nut blanks are adapted to be moved from these sleeves into thechucks by two horizontal feeding rods 37, whose forward.

ends projectinto the sleeves, and which are loosely supported in twosets of hearings or bosses 38 carried by a bracket 38 secured to theslide 22 which carries the facing tools. The rods 37 are adapted to bereciprocated with the slide, but are nevertheless yieldingly connectedto the parts which actuate them through the medium of coil springs 37which surround the rods and are located between-the rear set of bosses38 and collars 37" fixed to the rods and normally bearing against theforward bosses 38.

In consequence when the slide is moved forwardly toward the chucks, theyielding or cushioning springs move the rods in the same direction, andwhen the slide is retracted the rods are positively retracted by theengagement of the forward sets of bosses 38 with the collars 37 which,as before stated, are secured to the rods.

The sleeves 35 likewise have a limited endwise movement'with the rods37, the said sleeves being moved forwardly with the rods by springs 37which surround the rods between the sleeves and the adjacent bosses 38,and being moved rearwardly or away from the chucks by the rods whichhave pins 37.

extending downward into elongated slots of the sleeves. W

The construction is such that as the slide 22 moves forwardly the rods37 are moved forwardly by the springs 37 and the sleeves 35 are movedforwardly by the springs 37 until their forward ends are very close tothe jaws of the two uppermost chucks, which jaws are at such timeopened, as will be explained; The sleeves are moved forwardly untilflanges on the rear ends thereof engage the adjacent faces of the blocks36. As the rods v37 move forwardly they engage the lowermost nut blanksin the chutes, and push the same through the sleeves 35 into the jaws,or, in the event that the pol onal nut blank does not at once registerwit the polygonal opening in the chuck, the blanks are pushed up againstthe faces of the chucks and'immediately begin to spin or rotate with thelatter. However, the increasing pressure ofthe rods on the blanks, dueto the augmenting compression of the springs 37, causes the rotation ofthe blanks to slow down until the blanks and chuck openings come intoexact registration, whereupon the blanks are thrust into the chucks,moving inward the ejector blocks 19 and compress ingthe springs 19.

hereupon the jaws close onto the blanks and the rods are retracted,moving the sleeves 35 away from the chucks, so as to prevent a nut blankfrom striking the same, as the turret is rotated, in the event that ablank is not the full distance in the jaws of one of the chucks.

Durin the forward movement of the rods 37 at w ich time the lowermostblanks are moved into the chucks, the blanks immediately above thelowermost drop onto the upper sides of the rods, which sides arefiattened as shown in Figs. 6 and 7, and thence the rods are retracted asuflicient distance to bring the forward ends of the rods from beneaththe blanks resting thereon, whereupon the blanks drop down into thesleeves ust in front of the forward ends-of the rods, so that upon thenext forward movement of the rods, said blanks will be pushed into thechucks.

At or substantially at the time that the rods begin to move the blanksforwardly toward the chucks, the spindles of the two chucks which are inposition to receive blanks are given a slight forward movement towardthe blanks which are to be moved into the chucks, or toward the sleeves35, the forward movement being suflicient to enable the jaws of thechucks to open. The opening of the chucks to permit the blanks to bemoved therein is accomplished by a lever 40 which is pivoted between itsends on the frame 11 (see particularly Fig. 5) in the center plane ofthe machine, and which has a bifurcated upper end straddling the shaft20. At the upper end of this lever are two bosses 40 in which aremounted two adjustable threaded pins or bolts 40", the forward ends ofwhich are adapted to engage the rear ends of the two uppermost chuckspindles when the lever 40 is rocked. The lever 40 is rocked by a camdisk 41 which is mounted on shaft 32 and constitutes the direct supportfor cam 31 which actuates the mechanism for feeding the blanks from thehoppers 30. This cam disk 41 has on its rear face'a cam projection 41which at each revolution of the disk 41 engages a roller 40* at thelower end of lever 40, and as the roller rides up onto and over the faceof the cam projection, the upper end of the lever is swung forwardly andthe pins 40 move the two chuck spindles forwardly and hold them in thatposition until the two chucks have received the nut blanks. Whereuponthe roller rides ofi the cam projection as the latter rotates past thesame, and the lever is restored to normal position by a spring pressedplunger 42 which bears against the lower end of the lever and pressesthe same toward the cam disk.

While the two uppermost chucks are receiving the blanks as abovedescribed, the blanks in two chucks are being drilled and the drilledblanks in the remaining two chucks are being faced or crowned. At theconclusion of these operations which occur simultaneously, the turret isturned through an arc of 120 degrees so as to carry the blanks justreceived in the chucks to drilling osition, to carry the two drilledblanks to acing position and to carry the two faced blanks past thepoint at which they are ejected from the chucks and to bring the latterto the blank receiving positions. The turret is moved in this manner byan indexing mechanism including a rotatin disk or plate 43 which issecured to sha 32 and is provided with two rollers 43 which engage inradial V-sha ed slots 44 in an indexing disk 44 secure to the end ofturret 13. (See Figs. 5 and 9). The spacing of the coiiperating parts issuch t at the two rollers which engage the slots successively, give theturret the re uired 120 degrees movement at each revo ution 'of saidplate 43. To prevent any movement of the turret between intermittent 120degrees movements which the said turret is intended to have, the shaft32 is provided alon side the plate 43 with a lockin cam 44" having anarchaped periphera portion which, after the desired movement has been'ven to the turret and indexing plate 44, re ls or comes intoregistration with one of six "concave portions of the periphery of theindexing plate, each of which portions are turned or curved on a radiussubstantially equal to the radius of curvature of the arc-shapedperipheral portion of the locking cam disk 44*.

As the chucks pass from facing position to blank receiving position, thenow drilled and faced nut blanks are ejected from the chucks and arepermitted to drop into a suitable receptacle, not shown. The chucks aresuccessively opened to permit the ejectors 19 to eject the blanks fromthe ch'uclm by means of a roller 45 so located that as the chucks arepassing from the facing to the receiving positions the rear ends of thechuck spindles engage the periphery of the roller and in so doing aremoved forwardly a suflicient distance to allow the chuck jaws to releasethe blank and permit its ejection in the manner stated. As the spindlespass the roller the former are returned to their normal positions andthe chucks which have just been relieved of the blanks, next receive newblanks which during the next sequence of operations are drilled, facedand then ejected from the machine.

A brief description of the operation of the principal parts of themachine will now be given. The shaft 20, as well as the shafts 24 and 32are continuously driven, and in consequence, through the medium of thegears 20 and 20, the chucks are continuously rotated at a redeterminedspeed in one direction, and t rough the medium of the gears 25-and 25the drills are continuously rotated at a predetermined speed equalpreferably to the speed of the chucks, but in the reverse direction. Asa result, the blanks will'be drilled at a speed equal to the combinedspeeds of the drills and chucks, while the blanks will be faced at thespeed dependent upon the speed of rotation of the chucks. For thereasons previously stated, however, the average cutting speed of boththe facing tools and drills will be the same.

Assuming that the turret has just been turned by the indexing mechanism,two

empty chucks are in alinement with the feeding mechanism, the blanks intwo other chucks are in alinement with the drills, and the two drilledblanks in, the remaining two chucks are in alinement with the facingtools. At or substantially at the completion of the turret movement, theslides 21 and 22 are moved forwardly, so as to cause the drills to drillthe blanks in alinement therewith, and to cause the facing tools to faceor crown the blanks in alinement therewith. Thereupon the two slides areretracted, the slides being moved both forwardly and rearwardly by thecams on the continuously rotating shaft 24.

At or substantially at the completion of the said indexing movement ofthe turret, the two chucks which are about to receive the blanks areopened by the lever 40 which at the proper time is rocked by the cam 41which holds the jaws open until the blanks are inserted therein. At thesame time that the slides are moving forwardly to drill and face theblanks in four of the chucks, as has just been described, the slide 22compresses the springs 37 and 37, moving forwardly the sleeves ortubular members 35 at the lower ends of the chutes, and also the feedingrods 37 which extend into the said sleeves. The forward ends of thesleeves 35 are brought up close to the jaws which are now open as beforestated, and the rods 37 are caused to travel forwardly through thetubular members, the springs between the slide and the rods causing thepolygonal blanks to be either inserted immediately into the chuckopenings, or to be pressed yieldingly against the faces of the chuck andto be inserted therein as soon as the blanks are in alinement with thechuck openings. Thereupon the two chucks are closed, and when the slidesare retracted to move the drills and facing tools away from the blankswhich have just been drilled and faced, the rods 37 are positivelyretracted, and the latter move the sleeves 35 away from the chucks asu'ilicient distance to prevent engagement between the sleeves and aprojecting nut blank which perchance may not have been inserted or maynot have remained the full distance into the chuck.

The two blanks now having been inserted in the chucks, and the blanks inthe other chucks having been drilled and faced, the turret is again.moved by the indexing mechanism through an arc of 120 degrees, whereuponthe sequence of operation just stated is repeated.

During each indexing movement, and while two of the chucks are beingmoved from facing position to blank receiving position, the roller 45 isengaged by the two chuck spindles, causing said spindles to be movedforwardly so as to permit the corresponding chuck jaws to be opened, andto the ejector blocks 19 to throw the now drilled and faced blanks outof the chucks, the ejecto'r blocks being impelled forwardly as soon asthe jaws are opened by the springs 19 which were compressed when theblanks were previously inserted into the chucks.

I have described only one construction which by tests and usage hasproven to have very high efficiency, and to produce results satisfactoryin all respects. Nevertheless, I am aware that many of the parts can bemodified in construction, and I therefore do not desire to be confinedto any details of construction or arrangement, except as I am permitexpressly limited by the terms of the appended claims.
